Introduction.: Screening for COPD is currently considered to be insufficient. Electronic minispirometers allow screening for COPD in general practice. Objectives: To assess the prevalence of COPD in a population of at-risk patients in general practice (GP) and to identify the high-risk factors for the disease. Methods: A cross-sectional study was performed in a GP setting. Patients aged between 40and 75 years with a history of smoking, occupational exposure to toxic substances or chronic respiratory symptoms were offered airflow assessments by electronic mini-spirometry. For any value of FEV 1/FEV6 less than 70%, screening for COPD was considered as positive. Results: Of the 778 patients seen during routine consultations, 273 (35.1%) fulfilled the inclusion criteria. The test was positive in 128 of the eligible patients (46.9 %). The prevalence of proven COPD (ratio<70%) was 13.9% (38 patients). The high-risk factors were age over 60years (P= 0.03), body mass index over 28 (P= 0.04), smoking history of more than 30pack-years (P < 0.0001), presence of clinical signs (P < 0.0001) and industrial exposure to toxic substances (P = 0.03). Conclusions: Targeted screening of patients with risk factors for COPD can be performed in a GP setting. An electronic mini-spirometer is a reliable and inexpensive screening tool. © 2013 SPLF.
